DESCRIPTION OF THE PRIOR ART

Books without stiff cover, that is paperbacks, normally can not be placed standing up, that is supported on a narrow side egde on a surface or a book shelf without a suitable side support, for instance a book end or a neighboring book. If a suitable separate side support is not used a paperback normally will "collapse", if a neighboring book is taken out from the shelf, the book may be damaged permanently; and it is becomes difficult to replace the neighoring book. In particular this problem concerns larger paperbacks, for instance telephone books or similar large "soft" books or booklets.

The described problem may of course be solved by a kind of binding, where the book is provided with a cover with a back and a stiff front and back side member. This could be be obtained by means of a traditional bookbinding, or by means of a loose binder or cover, which may be mounted by the user, and which possibly could be reused for new or other books; but this would however be a rather expensive solution.
